COTTQN-S CRAPER ATTACHMENT.

ESPECIFICATION forming part of Letters Patent No. 308,920, dated December 9, 1884.

Application filed August 30, 1854. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. IlIClVIURRAY, a citizen of the United States, residing at 01inton, in the parish of East Feliciana and State of Louisiana, have invented certain new and useful Improvements in Cotton-Scraper Attachments for Plows, of which the following is a specification, reference being had therein to the accompanying drawings.

Thisinvention has relation to an attachment for ordinary plows, whereby they are adapted for use in cleaning rows of cotton as with the regular and complete cotton scraper, so that by means of the attachment a complete implement for the operations of plowing and cleaning the cot-ton is not required, as one of said implements may be made to serve both purposes.

The invention consists in certain features of construction hereinafter described, and specifically pointed out in the claim. Referring to the drawings, Figure l is a perspective of an ordinary plow provided with my improved attachment or cotton-scraper. Fig. 2 is a rear view of the cotton scraper, its standard being shown in perspective.

Like letters indicate like parts in both ures.

A represents the beam of an ordinary plow, to which by suitable clamps, as B, is secured a supplemental beam, 0, which is the beam proper of the cottonscraper attachment. The beam 0 is mortised at one edge thereof, as D, said mortise beinginclined so as to support the standard E of the cottonscraper in such a manner that its lower end is held in advance of its upper end, the whole standard being inclined to the front, as shown.

Through the beam 0 passes a clamp, O, which embraces the standard E, which is provided with a series of grooves, E, so that the clamp may rest in one or the other of said grooves, and the standard be supported at a greater or less elevation from the ground. By this means vertical adjustment of the stand ard E within the mortise D of the supple mental beam 0 is secured. The standard E is slotted, as at E and through the slot passes an adjustable brace, F, pivotally secured to the beam G at F, and threaded and nutted at its outer end, so as to be tightened and forcibly bind the standard E within. the mortise D,

and to overcome the strain in a direct line with the standard during the operation of the scraper. The lower end of the standard E is broadened and chamfered or beveled on its front face, so that the scraper proper, G,shall be disposed diagonally in front of and upon the standard. The lower broadened end, E", is perforated for the passage of a pivot-b0lt,G, upon which the scraper may be turned when adjusted, as hereinafter described.

G represents a slot, curved, as from G asa center, so that the bolt H passes through said slot and through the standard, and may be utilized to hold the scraper at desired positions of adjustment. The scraper is provided with a perforated portion, G through which passes a draft or brace rod, I, pivotally secured to the beam 0 at I, and provided with a sleeve, 1 and a nut, 1

The sleeve 1 may be made of any flexible material, as rubber or wood, or it may be disposed of entirely, and the nut I be placed in contact with the perforated portion G of the scraper.

After the beam 0 is secured to the beam A by the clamps, the plow may or may not, as desired, be inclined slightly, so as to throw it substantially out of operation, and the scraper G is then adjusted so as to bring its lower edge into such relation to the ground as to render it operative in use, and the nut His then tightened, when the scraper can be used as such, whilethe plow is inoperative; or both the plow and the scraper may be used simultaneously.

Having thus described my invention and its operation, what I claim is-- The combination, with an ordinary plowbeam, as A, of the supplemental beam, as 0, having the inclined mortise I), the notched standard E, clamp G, adjustable scraper G, pivotallyconnected adjustable brace-rods F I, and the clasps B B, whereby the attachment may be seen red to and projected in rear of the ordinary beam, A, without preparation, and may also be adjusted independently thereof, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
